The Agilent/Keysight ESA-L1500A is a portable spectrum analyzer that measures frequency content across 9 kHz to 1.5 GHz using super-heterodyne receiver architecture. Built for field deployment, it delivers rapid 5 ms sweep times and automatic input overload protection to prevent damage in demanding environments. The instrument combines a 15.8 cm high-resolution LCD display with intuitive hard key/soft key front-panel controls, enabling engineers to perform complex RF analysis without sacrificing portability or ruggedness.
